31 Claims.

The present invention relates to a machine for manifolding papers,documents. drawings and the like by means of an original printing plateor stencil sheet carrying the text to be printed in copyablemirror-writing. The text is printed on sheets or webs, which previouslyhave been moistened with a rapidly vola-tilizing fluid which easily anduniformly absorbs the printing ink without attacking the sheet or web.The moistening procedure is hereby performed in such a manner. that onlyan extremely thin film of fluid is applied to the sheet. The originalcopyable sheet, carrying the text to be printed in mirror-letters, isclamped to a printing cylinder and the sheets to be printed upon aremoistened by means of a moistening device and are thereupon fed betweenthe printing cylinder and a pressure roller. By means of this machine itis possible to produce a great number of exact and clear copies.

The machine according to the invention is of very simple constructionand may therefore be manufactured at lower costs than the manifoldingmachines hitherto known. The novel machine may also be handled withgreater ease than the complicated machines hitherto used.

An important feature of the present invention is the clamping device bymeans of which the original copyable sheet is fixed to the printingcylinder. I have found, that it in the most cases is sufficient to fixone of the ends of the original mirror-writing copyable sheet to theprinting cylinder. According to the invention the clamping devicecomprises a deflectable or pivotal clamping member. which in operativeposition lies flush with the surface of the printing cylinder.

Hitherto it was necessary to open and close the clamping devicemanually. According to the present invention the clamping device isopened and closed automatically in that the opening is performed byimparting a partial backward rotation to the cylinder. Whereas theclosing is performed by rotating the cylinder from its normal positionforwardly. It should however be understood, that it is also within thescope of the invention to so arrange the clamping device that it may beopened and closed manually.

If it is desired to clamp both ends of the copyable sheet to theprinting cylinder the other end of the sheet may be clamped by means ofa clip or the like. which may be adjusted and locked in any desiredposition on the periphery of the printing cylinder. By means of thisclip copyable sheets of different lengths may be clamped to thecylinder.

In Germany January The printing cylinder may at any moment be broughtback into its original position when it is desired to fill out schedulesor printed forms on previously arranged lines.

The pressure which the pressing roller exerts on the printing cylindermay be adjusted as required and the pressing roller may be alsoadjusted. The pressing roller may also be adjusted in a horizontaldirection in relation to the printing roller in order to compensate forinaccuracies created during the mounting of the machine. The pressurebetween the cylinder and the pressing roller may at any moment bereleased by means of a special device.

In the hitherto known manifolding machines great difficulties areencountered in exchanging the moistening strip projecting from thereceptacle in which the moistening fluid is stored. This strip, whichusually consists of felt or the like, is rapidly worn and becomesdamaged and must therefore frequently be exchanged. In the knownmachines the entire moiste'ning device must be removed from the machineand be dismounted before the moistening strip can be exchanged.According to the present invention the moistening strip can be easilyexchanged by a simple manipulation without separating the moisteningdevice from the machine.

In the manifolding machines hitherto known the fluid for moistening thesheets to be printed upon is fed to the fluid receptacle of themoistening device from a dropping container the outlet of which may beopened or completely or partially closed by the operator. This containeris arranged at one side of the machine and at a higher level than thelatter. If inadvertently more fluid is fed into the fluid receptaclethan the filler in the same is able to absorb the fluid will flow overthe rim of the receptacle and too much fluid will be applied to thesheets to be printed upon, so that blurred prints will be obtained.According to the present invention this objection is avoided byarranging the container in which the fluid is stored below the machineand feeding the fluid to the moistening device through a wick or thelike. The fluid receptacle is filled with an absorbent, for instancewith felt or cotton.

By this arrangement only so much fluid will be drawn from the containeras the material in the fluid receptacle is able to absorb and todistribute and the surface of the sheets to be printed upon will beuniformly covered with an extremely thin film of fluid. The supply offluid may be interrupted by lifting the wicks out of the container or bylowering the container until the wicks are completely separated from thefluid stored therein.

It may sometimes occur that the sheet to be printed upon is wrinkled andin this case the moistening strips may be damaged. According to theinvention therefore a special device is provided by means of which thefluid container may be manually lifted from the sheet and the printingcylinder and the pressing roller may be separated from each other, sothat the wrinkled sheet may be removed before any damage has been done.

A constructional form of the invention is shown schematically by way ofexample in the accompanying drawings, in which Fig. 1 is a lateralsectional view of the complete machine.

Fig. 2 is a sectional view showing the adjusting or setting mechanism.

Fig. 3 is a front view of the moistening device.

Fig. 4 is a sectional side view of the moistening device.

Fig. 5 is a detail sectional view of one of the bell crank levers, theframe and the bearing bolt.

I denotes the printing cylinder, the shaft of which is arranged inbearings in the lateral frame members I5 of the machine. The cylinder isloosely arranged on its shaft and is rotated by means of a handle orcrank 3.

The printing cylinder is adjustably arranged, so that the printing levelmay be regulated and the printing may take place on lines previouslyformed on the sheet. By means of a worm III-I I and a worm wheel 9 theprinting cylinder may be adjusted within certain limits, so that theprinting operation commences at a predetermined moment. The worm wheel 9carries the control member I2 with the control opening I2. After eachrevolution the cylinder I is arrested exactly in the same position by apin I3 snapping into the aperture I2. The pin I3 is operated by thespring I3 the pressure of which may be regulated by means of the nutsI4.

The pressing roller 2 is rotatably arranged in bell crank levers 4,which are pivotally arranged on the eccentric bearing pins of threadedbolts 30. The bolts 30 are seated in the lateral frame members I5 of themachine. The pressing roller may be adjusted toward and from theprinting cylinder by means of the bolts 30. The pressure of the roller 2against the cylinder I and the vertical position of the roller 2 may beregulated by means of the set screws 6. The screws are held securely inthe chosen position by means of lock nuts I. In order to relieve thecylinder I from the pressure exerted by the roller 2 without alteringthe setting of the screws 6 the latter are carried by a shaft 5 which isarranged in bearings in the members I5. This shaft may by means of alever 8 be deflected upward, whereby the roller 2 is separated from thecylinder I. The roller 2 may again be brought into engagement with thecylinder I by lowering the lever 3 until it abuts against the stop 8'.

Figs. 3 and 4 show a preferred constructional form of the moisteningdevice according to the invention. The moistening strip 26 is held by acarrier 22 of sheet metal or the like. The carrier 22 is somewhat morebent than required on account of its connection with the cross piece 2|to which it is fastened and the moistening strip 26 will therefore bythe carrier 22 be resiliently pressed against the lower part 24 of thefluid receptacle whereby the strip 26 is held in a fixed position. Thecarrier 22 is fixed to the crosspiece 2I by means of a lever 20, whichis adapted to be brought into engagement with the wedgcshaped faces 23.The lower part 24 of the carrier is fixed to the cross piece so that aclosed container is formed and the moistening strip 26 projects from thenarrowed end of this container. The carrier 22 is bent outward at itsends, whereby a guide 22' for the strip 26 is formed. The empty space inthe fluid receptacle is fllled with an absorbent material for instanceth a body 0 fe tfi'e like which is formed afir the 1n t 'e ri'or"of"thereceptacle. The receptaclevvilf therefore always contain a certainamount of fluid and this fluid will be evenly distributed. The crosspiece 2I, which is deflectably arranged between the lateral framemembers I5, carries a control lever I8 by means of which the moisteningdevice is lifted when the wheel I1 rolls over the curved part 16 of thecontrol mcm- .J'

ber I2. As soon as the printing cylinder I is rotated the wheel I!leaves the control member l6 and the front end of the moistening deviceis lowered onto the sheet under the influence of the springs 29. When awrinkled sheet appears 1 the moistening device is lifted by means of thehandle I8 on the control lever I8 and the cylinder I is rotated inbackward direction, whereupon the wrinkled sheet may be removed. Throughthe wicks 25 the fluid in the container 28 is sucked into the fluidreceptacle and on account of the absorbent material in the receptaclethe fluid is rapidly and uniformly distributed in the moistening strip.If it is desired to interrupt the supply of fluid the wicks 25 may belifted out of the container 28 or the container may be lowered until thewicks are separated from the fluid.

The original printing sheet or stencil sheet is placed on the cylinderwriting on the outside and one end of the sheet is clamped to thecylinder by means of the clamping bar 33 which is deflectably orpivotally arranged in bearings 39. The clamping device is opened andclosed automatically. When an angular movement in backward direction isapplied to the cylinder I the lever 34, which is fixed to the member 33and carries the pin 35, will contact with the lever 36 and ride over thesame, whereby it is lifted together with the clamping member 33, so thatthe original printing sheet may be inserted without difficulty. When apartial rotation in forward direction is imparted to the cylinder I theclamping lever 34 will again slide downward on the lever 36.

and the clamping member 33 will by a spring 38 be pressed into acorresponding groove in the cylinder I and take up a position in whichit lies flush with the periphery of the said cylinder. When themanifolding operation is started and the printing cylinder I performs arevolution the lever 34 with pin 35 will push the lever 36 aside, whichby means of the spring 40 again is brought back into its normal positionin which it rests on the pin 31.

On one or both end faces of the printing cylinder I a clamp holder 4! isrotatably arranged on the shaft of the cylinder. In this clamp holder aseries of grooves or apertures 42 are arranged which are adapted tocooperate with a ball 43 resiliently seated in the member 4I. By meansof this arrangement the clamp position may be adjusted. The upper end ofthe clamp 43 is bent over the mantle face of the cylinder and is pressedagainst the same by the spring I with the 1nirror- 44. This arrangementserves for clamping the stencil sheet to the cylinder l at any desiredpoint on the sides of the latter.
